CPS Data Notifications

CM VES Message

https://www.rfc-editor.org/rfc/rfc8641

O1 CM Update Notification VES Message

DMi Data AVC Sample Message

SON Use Case Weekly Meeting Notes

Assumptions

#

Issue

Notes

Decisions

1

VES Event is received via Strimzi/DMaap Kafka on DMI.

Yes. This is agreed.

2

Changes in CM data will result in CPS-Core sending a CPS Data AVC irrespective the origin of the change.

See #4 in the Bigger Picture below.
This could later be model controlled to be more granular.

Agreed.

Issues & Decisions

Issue

Notes

Decisions

1

CM VES Message format schema.

Who will own it ?

In order to process the message DMI plugin / NCMP should be aware of the schema of the incoming message it is going to be consume.

VES format primary reference is here: [INT-2180] Define CM VES message aligned with 3GPP/O-RAN O1 - ONAP JIRA

2

Topic from where we will receive the CM VES Message.

Existing channel or channel owned by NCMP/DMI

Vishal Varvate to provide the topic details.

Priyank Maheshwari ,please use below topic

unauthenticated.SEC_3GPP_PROVISIONING_OUTPUT

3

Mapping of the relevant information from the CM VES Message

CmHandle
Xpath
Operation that happened

Only fields that seem to suggest to have these info. are.

moiChanges.operation
moiChanges.value
moiChanges.path ??

Related work in ONAP suggests this possible alternative schema:

https://wiki.o-ran-sc.org/display/SIM/Network+Slicing+Use+Case#NetworkSlicingUseCase-ExampleVESPMstndDefined

So wanted to confirm if measurements.measurement-type-instance-reference is xpath?

Mapping detailed below: VESEvent%E2%86%92DMIDataAVCMapping

For more details and descriptions see CPS Data Notifications Overview

VES Event Flow

DMI Plugin to receive CM VES Message from the upstream( VES Collector ?? ) via a REST call or DMI will listen to a topic. ( or also can generate a VES message for testing)
DMI Plugin will have to convert the CM VES Message to DMI Data AVC event and publish the same to an internal topic.
NCMP will have logic to handle the DMI AVC event received to update the cache. ( See #6 in CPS Data Notifications Overview )

The DMI Data AVC Payload is defined by https://www.rfc-editor.org/rfc/rfc8641

Value Copied VES Event

Transformed VES Event Value

Value Generated by DMI-Plugin

Analysis

Dataspace : NFP-Operational
Yang Resource : ran-network to be used. ( trimmed down version just like cps-ran-schema-model )
We need to have a defined channel/topic where the VES messages are present , and NCMP should be able to listen , interpret/process and call the relevant CPS-Core APIs in order to publish the changes in the CPS DB.
